EL Tape is an incredibly versatile material it can be wrapped around things.

To join it to a costume we recommend our ''''sewable-loop + stickable-hook'''' velcro which allows you to sew one part of the velcro to your costume while the stick pat goes on the back of this tape. The tape can then be removed from the costume to wash it

EL Tape can even have holes and shapes punched into it and be cut to your chosen shape
